I am trying to get processes attached with a port 7085 on SunOS. i tried following commands.

netstat -ntlp | grep 7085 didn't return anything

netstat -anop | grep 7085 tried this one also. This switches are not valid in SunOs

I am getting the following output.

#netstat -anop

netstat: illegal option -- o

usage: netstat [-anv] [-f address_family]

netstat [-n] [-f address_family] [-P protocol] [-g | -p | -s [interval [count]]]

netstat -m [-v] [interval [count]]

netstat -i [-I interface] [-an] [-f address_family] [interval [count]]

netstat -r [-anv] [-f address_family|filter]

netstat -M [-ns] [-f address_family]

netstat -D [-I interface] [-f address_family]

The version of SunOS is SunOS 5.10. I believe netstat is the only command can do this.

What is the exact switches for netstat which will give me the process id attached with port?

pfiles /proc/* 2>/dev/null | nawk '
/^[0-9]*:/ { pid=$0 }
/port: 7085$/ { printf("%s %s\n",pid,$0);}'
  • pfiles /proc/* is retrieving all processes file descriptors details
  • 2>/dev/null is dropping out errors due to transient processes died in the meantime
  • each line starting with a number followed by a colon reports the process id and details, it is stored in the awk pid variable
  • when a line ends with the string port: <portnumber> (here is 7085), the corresponding pid variable is displayed.

Note: you need the required privilege(s) to get port information from processes you do not own (root has all privileges).

    the script i am using internally it is using pfiles to get the details. – LOGAN Nov 07 '12 at 10:00
  • @jiliagre. This one is working fine as expected. If you can give an explanation of this script, it will be possible for me to change it as per my needs in future.. – LOGAN Nov 08 '12 at 04:48

Have a look on lsof http://linux.about.com/library/cmd/blcmdl8_lsof.htm command.

This command describes which processes are using which file descriptors. Remember that anything on port 7085 will have its own file descriptor which you can use to trace back to the process using it.

I would try something like: 

$ lsof -i :7085

Hope it can help.

  • Yes. I tried that unfortunately the command was not available. I would have installed this package but it is production server and i dont have rights to install anything on the server and there is not only 1 server there are more than 200+ servers. I am trying get a help with the available commands on solaris... – LOGAN Nov 06 '12 at 16:49
  • @LOGAN Have you got fuser? Try this one: fuser -4 -v -n tcp 7085 – andrefsp Nov 06 '12 at 17:07
  • it is not working. I got following out put.fuser: illegal option -- 4 `Illegal option ?. Usage: fuser [-[k|s sig]un[c|f|d]] files [-[[k|s sig]un[c|f|d]] files]..` – LOGAN Nov 07 '12 at 05:33

I got his script from HERE . Log into solaris system. Open vi editor. Go into insert mode. Copy and paste this script. save the file and give the name PCP. Give execute permission. Run this script with -p or -P swithc. It will give an output with the PID, PROCESS Name and Port.

Make sure you need to be in ksh shell to execute it.

PCP is a script that enables administrators to see what open TCP ports are in use on a Solaris system. It maps ports to PIDs and vice versa. It accepts wildcards and will also show at a glance all open ports and their corresponding PIDs. It is nice script gives a very fine out put. Just try it.

Example: #pcp -p PORT_NUMBER or #pcp -P PROCESS_ID

#!/usr/bin/ksh
#
# # PCP (PID con Port)
# v1.10 08/10/2010 Sam Nelson sam @ unix.ms
#
# If you have a Solaris 8, 9 or 10 box and you can't
# install lsof, try this. It maps PIDS to ports and vice versa.
# It also shows you which peers are connected on which port.
# Wildcards are accepted for -p and -P options.

# Many thanks Daniel Trinkle trinkle @ cs.purdue.edu
# for the help, much appreciated.
